Sen. Jim DeMint (R-S.C.) said he's "disappointed" that Rep. Michele Bachmann (R-Minn.) -- who's running for the Republican presidential nomination -- hasn't signed her name to the "Cut, Cap and Balance" pledge during an appearance on CNN's "American Morning" on Wednesday.
Standing behind the "Cut, Cap and Balance" pledge entails opposing any debt limit increase without significant spending cuts, enforceable spending caps and congressional approval of a balanced budget amendment.
Bachmann, who has already cast a vote against raising the nation's debt limit, has signaled her reluctance to sign the pledge stems from her belief that it doesn't go far enough.
DeMint, a conservative favorite who waded into several high-profile GOP primary races in the last election cycle, has made clear that not signing onto the pledge is a "dealbreaker" for earning his support in 2012.
"We have to stop spending more than we're bringing in," he explained on Wednesday morning.
